I recently picked up VLC to help me extract audio from a DVD for the first time. It took me a bit of trouble to figure out how to get VLC to do this. I took the time to write down a bit of what I learned in the Extract audio page of the VideoLAN wiki.
I'd appreciate a review, if anyone is interested. If you have corrections, please apply them to the page, or discuss in the page's Talk page. It is, after all, a wiki.
